Season four of The Crown has propelled Princess Diana's marriage to Prince Charles to the forefront again. The couple became parents in 1982 with the birth of Prince William, followed by Prince Harry in 1984.
Diana enjoyed a close relationship with her sons before her tragic death in 1997. The Princess wanted her children to have as normal an upbringing as possible and treated them to days out at theme parks, sent them to public school and took them on royal tours.
In turn, William and Harry have honoured their mother's legacy by continuing some of her most vital charity work.
